VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 258,713, dated May 30, 18 82.

Application filed August 9,1881. (Model) To all whom it may concern:

Be it known that I, WALLAoE CLAYPooL, a citizen of the United States, residing at North Bufl'alo,in the county of Armstrong and State of Pennsylvania, have inventedcertain new and useful Improvements in Vehicle-Brakes; and I do hereby declare the followingto beafnll, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertai'ns to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a perspective showing the present invention as applied in use, Fig. 2 is a plan view of the device represented in Fig. 1.

This invention relates to improvements in vehicle-brakes, and has for its object the production of a device whereby is furnished a simple and efficient means for adjusting either brake-shoe separately or both together, thereby taking up all wear and compensating for irregularity therein.

The invention consistsin the construction hereinafter set forth and claimed.

In the annexed drawings, the letters A A represent the rear wheels ofa vehicle-gear supported by the axle B, from which extend the bars I I to the bolster, and forming the forked reach. At the front these bars support a hanger, h, to which is pivoted the lower end of the brake-lever H, having the handle it, which is to come within convenient reach of the operator.

The letter G represents a forked connectingrod, consisting of a stem, 2, and branches 9 g. The front end of the stem 2 passes through the lever H, and is held adjustably thereto by the nuts 9'. The rear ends of the branches g g pass through the ends of brake levers F F, and are held adjustably thereto by nuts g. These levers F F are pivoted to fulcra b b on axle B, and carry shoes E, which are adapted to bear against bands D, secured on the inner ends of the hubs of the wheels A. This construction and arrangement furnishes an eificient means of adjustment, forif it be desired to vary the pressure on both wheels alike, or to compensate for similar wear on both shoes or hands, the nuts g are turned and the position of stem 2 varied; but if it be desired only to make the variance at one wheel, one set of nuts, g, is turned. In this way the device can be changed to suit any degree of pressure or wear.

Iam aware thatbrake mechanisms have been patented where there is provision for wear; but, so far as I am aware, there has been no means devised before this for affecting either or both brakes at will.

Having described my device, what I claim, and desire to secure by Letters Patent, is-

The forked rod G, havin g stem 2 and branches 9 g, in combination with the hand-lever H, brake-levers F F, and the triple sets of 'nuts g g g, wherebyis forme'da. device for operating the brakes in which either or both brakes can be adjusted at will, all as set forth and described.

In testimony whereof Iaffix my signature in presence of two witnesses.

WALLACE OLAYPOOL.
